Metal foil low resistance chip resistors (short-side terminals)
■
KRL series
AEC-Q200 Compliant
Features
●
The C type utilizes materials that withstand high temperatures and
can be operated up to 175°C. The M type utilizes low emf materials
that are stable up to 155°C. TCR is very stable for very low resistance:
+/-100ppm°C for 5mΩ
〜
9mΩ, and +/-50ppm°C for 10mΩ
〜
. Face down
mounting allows for accurate current measurement. Long and short side
terminal types, as well as power ratings from 1/3W to 5W are offered to
meet customers’ specific requirements. The protective outer coating is
halogen free in consideration of the environment.
Applications
Current sensing surface
mount resistors
●
PCs, hard drive discs, audio visual equipments, power sources, inverters, automotive
electronics, industrial machining equipments, industrial test and measurements, etc.
